CAR-COUPLlNG.

aPECIPICATIQN forming part of Letters PatentrNo. 315,647, dated April 14, 1885.

Application filed February 26, 1885.

To all whom it may concern:

Beit known that I, ORTN DATUS DAVIS MAR.- TIN, a citizen of the United States, residing at Augusta, in the county of Richmond and State 1 tion, effective in its operation, and one that will be strong and durable.

With these ends in view the invention consists in the improved construction and combinations of parts, hereinafter fully described,

and point-ed out in the claims.

In the drawings, Figure 1 is a perspective view of a car-coupling constructed in accordance with my invention. Fig. 2 is a longituditudinal vertical section of the same. Fig. 8 is a transverse vertical section.

In the accompanying drawings,in which like letters of reference indicate corresponding parts in all the figures, A represents the drawhead, which is,as usual,provided with a flaring mouth, a.

Within the draw-head A is mounted a sliding block, B, which has a recess or seat, b, at its rear end, in which recess or seat is located one end of a spiral spring, 0, the other end of said spring bearing against the closed rear end of the drawhead.

Upon the upper side of the draw-head A, near the forward end thereof, are provided two upwardly-extending snpports,G, which are connected near their upper corners by shafts, upon which are mounted idle-rs d.

I) represents a coupling-pin, the lower end of which is adapted to extend through a hole or opening in the draw-head. The said coupling-pin D is divided near its upper end, and in said divided end is pivoted a hook, c.

Upon the coupling-pin D,justbelow the divided portion, is provided an annular shoul der, 6, against which is adapted to hear one end of a spiral spring, E. The other end of this spiral spring E bears against the under side of a cap, F, which incloses the upper end of the supports 0, and is secured thereto, so

[No model.)

that it may be removable therefrom,10y means of pins or holtsf.

Upon the coupling-pin D, just below the air nular. shoulder c, is provided a plate, G, having holes or openings at its ends, in which holes or openings are secured chains 5 which pass over the idlers mounted between the supports, and may be connected at their outer ends to hand-levers H, pivoted bet-ween outwardlyextending cars at the lower ends of the drawhead. It will'thus be seen that when thelink carried by the adjacent car strikes the sliding block B and forces the same rearwardly beyond the coupling-pin D said coupling-pin will be forced downwardly into engagement with said link by the spiral spring E, and that by operating either one of the hand-levers said coupliugpin will be released from. engagement with the link and the sliding block forced to the forward end of the draw-head by means of the spring 0.

In the draw'head A, near the forward end thereof, is provided a vertical passage or opening. h, in which is located a coupling-pin, i.

Upon the front of the car are provided outwardly extending brackets I, in which is journaledashaft, J, having a cranlnK, which crank is located directly over the couplingpin D.

Upon the crank K is mounted alcver, L, the upper end of which extendsthrougl'l a guidebracket, M, secured to the front of the car. The lower end of this lever is provided with an outwardly-extending arm, 5 providednear its extremity with a hole or opening, in which is secured the end of a chain adapted to be attached to the couplingpin A chain,j, also connects the lower end of the lever L with the couplingpin D, from which it will be seen that said pins D andi may be raised si multaneously, or that they may be operated independently of each other by detaching either of the chains. The ends of the shaftJ extend beyond the outer brackets, I, and upon said outer ends are mounted arms N, which, when the cars are coupled, rest or bear against the front of the car. The said arms are rigidly secured upon the ends of the shaft, so that by operating-i. 0., raisi ngcither of them the coupling pin or pins will be withdrawn from engagement with the link.

From the above description it will be seen that the cars may be uncoupled from either side or from the top, and that the devices described are simple in their construction and effective in their operation.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is.-

1. In a car-coupling, the combination, with a draw-head having a spring-actuated block located and adapted to slide therein, of a coupling-pin having an annular shoulder, supports on the upper side of the draw-head, a removable cap having an opening, a spiral spring mounted on said pin, said coupling-pin also having a divided upper end, and a hook pivoted in said end, substantially as set forth.

2. In a car-coupling, the combination, with a draw-head having a spring-actuated block located and adapted to slide therein, and supports covered by a removable cap having an' opening, of a coupling-pin having an annular shoulder, a spiral spring on said pin, a plate located on said pin below the shoulder, and pivoted levers connected with said plate, substantially as set forth.

mounted upon the upper end of said pin, a

plate on the pin below the shoulder thereof, chains secured to said plate, and pivoted levers adapted to be connected with said chains, substantially as set forth.

4. In a car-coupling, the combination, with a draw-head and the coupling-pin, of a shaftlocated in brackets secured to the front of the car, a crank on said shaft, a lever connected with said crank, connections between thelower end of said lever and the pin, and arms on the end of said shaft, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
